Answer:
X=-3
Step-by-step explanation:
To find the unknown variable: X, we need to see how mich 4x equals to. to do this, we must first subtract 3 from both sides of the equation. The left side will be left with -12, and the right side will be left with 4x. This means:
-12=4x So...
x=-3
To check if this is right, you can subsitute this back into the equation.
4 times -3= -12. -12=3=-9
